AUTO HEADLIGHT-DEFLECTOR DEVICE.

Application filed February 16, 1924. Serial No. 693,278.

To all 107mm it'may concern:

Be it known that I, CHARLES A. HART- MANN, a citizen of the UnitedStates, residing at Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in AutoHeadliglitz-Deflector Devices, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to an automobile headlight deflector device, andthe object of the invention is the improvement of a de flector device,which will give a great amount of light on the road without producing aglare that is confusing to the chauifeur of an approaching motorvehicle.

Another object of the invention is the provision of simple and eliicientmeans for indicating to an approaching chauffeur in an on-coming motorvehicle the exact position on a road of a motor vehicle provided with myinvention.

This invention is an improvement along the lines of the inventiondisclosed in my copending application, Serial Number 683,361, filedDecember 29, 1923.

lVith theseand other objects in view, my

invention comprises certain novel combinations, constructions andarrangements of parts as will be hereinafter described, illustrated inthe accompanying drawings, and more particularly pointed out in theappended claims.

In the drawings:

Figure 1 is a sectional view of a device constructed in accordance withthe present invention, showing the same in an ordinary headlight.

Figure 2 is a View, in front elevation, of a deflector deviceconstructed in accordance with the present invention, while Figure 3 isa side view of the same.

Figure 4 is a fragmentary, perspective view of the ring-like body of thedevice.

Referring to the drawings by numerals, 1 designates the ease of a lampin which is positioned by deflector device 2. The de flector device isplaced behind the lens 3 as clearly shown in Fig. 1. The deflectordevice 2 comprises a conical-like body 4i which is provided with anoutwardly-extending flat flange 5, formed integral with the outer edgeof said body 4.

I position horizontal blades 6 and 7 across the lower part of the body,having the prongs or extensions 8 extending through the body 4 forsecuring the blades fixedly in position. These blades 6 and 7 slantdownwardly from their rear to their front edge, whereby rays from thelamp are thrown downwardly upon the road.

In the center of the body, and arranged in a vertical position, is aslatted device which 1s formed or stamped from a single piece of metaland which comprises a pair of verti cal side blades 9, 9, and connectedto these blades are webs 10 from which extend slats 11. These slats 11project outwardly and downwardly for throwing the rays of the lampdownwardly upon the road. The blades 9 extend outwardly from their rearedge to their front edge, and the same is true with reference to thevertical blades 12, whereby the light rays are spread over the roadway,giving a large area of illumination without any glare occurring on thechauffeur of an approaching motor vehicle. It will, therefore, be seenthat I have provided, in a deflector device, means for deflecting therays downwardly upon the center of the roadway as well as spreading therays laterally over a broad area of the same.

The blades 9 and 12 are provided with the prongs or extensions 8 thesame as blades 6 and 7 for holding the blades in position upon thefinished device.

It is desired to provide means upon the lamps, whereby the chaufieur inan approaching motor vehicle can tell at once the exact position of theapproaching automobile and this is accomplished by providing a coloredtransparent strip 13 which is preferably provided in its center, with astarlike opening 14. I use the term strip in a broad sense, meaning apiece or body of material which can be of any color. It is to beunderstood that I preferably place a red strip on the left-hand lamp, asthis lamp will be close to the approaching, or passing automobile, andon the right-hand lamp I place a green colored piece or strip so thatthe approaching chauffeur can readily calculate the position of the earapproaching him. Integral prongs 15 extend preferably outwardly from theflange 5 and by bending over these prongs, against the coloredtransparent means 13 the same can be securely held in position upon thebody of the device. These clips 15 constitute clamping fastening meansfor holding the indicating means upon the body.

I have found from practical experience trated thesame in theaccompanying: draw ings, certain minor changes or alterations may appearto one skilled in the art to which this invent1onrelates,; during theextensive 'manufacture ofthe same and I, therefore reservethe right tomake such alterations or changes as shall fairly fall within the scopeof the appended claims.

That I claim is:

l.-1n a headlight deflector construction, a

ring-likeibody, horizontal deflecting strips-1 extending acrosssaid bodyin spaced relation to the'lower point thereof and disposed forwardly ata downward incline, vertically disposed deflecting strips extending. up-

Wardly from the upper one of said horizontal strips and having theirupper ends anchored to said body,the last-mentioned horizontalstripbeing; positioned below the cen-- ter of the space enclosed by thering like body, and horizontal deflector strips extendingbetween-certain of said vertical strips and disposed in spaced relationto each other from a point adjacent the upper point of said bod-y to a-point adjacent the upper horizontal strip.

2. In a headlight deflector construction, a

ring-like body, horizontal deflecting strips extending across the lowerportion of said body and extendingforwardly at a down ward incline,deflecting. means positioned above the upper one of said horizontalstrips, said deflecting means being formed of a single piece of materialand having verticall-y disposed side strips diverging forwardly andprovided with attaching -1neans at their ends for engagement with theupper horizontal strip and body ring cross strips having upper portionsattached to the side strips and lower portions bent to extend forwa-rdlyat a downward incline and other vertical deflector means positioned atoppo site sides of said deflecting. meansand disposed parallel to theside strips thereof for directing light towards the sides of a road.

In testimony whereof I hereunto a'liix my signature.
